- Description:
-
Students are introduced to the basic principles of data compression. They will learn the necessary theoretical background and get an overview of data compression methods being used in practice. The overview covers principles of integer coding and of statistical, dictionary, and context data compression methods. In addition, students learn the fundamentals of lossy data compression methods used in image, audio, and video compression.
- Contents:
-

3. [2] Statistical methods: Shannon-Fano coding, Huffman coding, arithmetic coding.
4. [2] Dictionary methods: LZ77, LZ78, LZW.
5. [3] Context methods: PPM, DCA, ACB.
6. Burrows-Wheeler compression.
7. Pattern matching in a compressed text.
8. Word-based compression.
9. Introduction to lossy compression (image, audio, video).
